I hope I'm not being confronting by asking this, are you agrophobic?
Like your husband I'm the talker in our house and have always chatted to all and sundry everywhere, standing in the supermarket cue, waiting in the street, on public transport, shop workers etc etc... can't help myself, my mother relates stories of things I said to people when very small.
I've met some extraordinary people with stories that should be on Australian Story, amazing!
But love my privacy and can get a bit hermity, get homesick within days when I go on holidays and generally prefer to entertain than go out and be entertained. DH to get out is like pulling teeth, once there he usually enjoys himself but I'm the one who mostly goes out of the property. And I have most of the contact with our clients.
I think in rural areas, it's 'really' important to keep in touch with people. You don't have to live in their pockets nor them yours but a contact even every couple of weeks with neighbours is really good. You hear everything that's going on and there's often things that you only find out by talking to neighbours, such as if there's something going through the cattle (disease) or someone's lost a pet etc etc.
Our old neighbour was a km away, nice distance and if he didn't see us for a couple of weeks would come over, have a coffee and tell us all the local 'gossip'... everyone stopped at his place as they drove past.
The night his roof got blown off, he came down to us and stayed for a couple of days... when we had a bush fire close our other neighbour (who'd almost finished buiding) and DH worked together to get it under control, they also worked together on setting up some water issues to work for us both as well.
Now I see my neighbours at craft once per month, the odd phone call if somethings happening. One was quarantined with Qld Cattle Tick (big problem) and let me know everything the LHPA said and did etc etc. Which was really helpful.
We're yet to go to the local BBQ held every two weeks, but try to be involved in the odd thing.
For rural living, you depend on your neighbours, if your house is on fire they'll likely to be there before the fire dept (know from experience). You don't have to have a big social life with them, but you need to share a cuppa and have a yak at least once a month.
Just my thoughts.
